At Sensors Expo 2018, Masakazu Shiinoki, a field application engineer from the MEMS Sensor Business Unit of Omron shows how different microelectromechanical systems (MEMS) sensing technologies can be used in a building. The three (ground, first and second) floors use barometric (absolute pressure), airflow and differential pressure sensors. In addition, the first floor has an […]
New flow switches from Balluf warn users of reduction in flow
The newest flow switches from Balluff alert users to potential failures due to a reduction in necessary fluid flow. The recently released BFF series of flow sensors, which are available in both thread-in and inline versions, provide a switching output that is activated when the flow falls below a user-defined rate. This makes it possible […]
What is a spirometer?
A spirometer is used to make the most common of pulmonary function tests (PFTs). It is a respiratory flowmeter that determines how well the lungs are working by measuring the amount of inhaled air, amount of exhaled air and how quickly it is exhaled. Used to diagnose asthma, chronic obstructive pulmonary disease (COPD) and other […]
How do you calculate flow from a pressure measurement?
A variety of techniques are used to measure flow, including: the Coriolis Effect, mass air flow, vortex, magnetic, thermal, ultrasonic, turbine and positive displacement meters as well as pressure sensors. With the high volume, low cost and reliability of microelectromechanical system (MEMS) pressure sensors, these products are a frequent choice for measuring both liquid and […]
How can multiple sensor measurements be used to improve air quality ?
At CES 2017, Vincent Maxime, Product Manager from Enerbee describes how the use of airflow, temperature, humidity, CO2, volatile organic compounds (VOCs) and pressure measurements with the Bluetooth connectivity of the Enerbee Smart Vent can provide a visual indication of the healthy or unhealthy status of various rooms in your home.
Proximal Flow Sensors Now Available for Neonatal Applications
Sensirion will be attending the MD&M West 2017 trade fair in order to present a proximal flow sensor for flow measurements in respiratory applications used in neonatology and pediatrics. This fully calibrated SFM3400 sensor is available as a single-use and reusable solution, and is highly robust, accurate and extremely fast in processing signals. It is […]
Measure Airflow with Pressure Sensor
At Sensors Expo 2016, Bernd Zimmerman, a field application engineer from Sensirion shows how the company’s SDP3x differential pressure sensor can be used to measure air flow in medical and other applications. An evaluation kit with the sensor, an interface and viewer software is available to simplify design-in. For more information, click here.
